Just off the ramp on sol 2 we see a text box saying 'sol 2: A2'. The black dot shows the location of the end of the drive on that sol, and we learn that the second APXS measurement was made there (A1 was a test on the lander). Just above it a small box is also labelled A2 - that is the actual location of the sensor, so it was a soil measurement. A3 was on a rock. Keep in mind the rover is bigger than those dots! They took 2 attempts to get one on Yogi.

This is the first section of the Sojourner rover's route map. The lander bounced and rolled across the surface until it came to rest. It deflated its airbags and unfolded - the airbags are still visible around the lander base. On sol 1 Sojourner was on the lander. On sol 2 it drove off, and here we can follow it across the surface. Its APXS instrument was on a short arm which could be rotated down to touch the target - soil or rock (A1, A2 and so on).

This is the 4th set of Sojourner rover images, taking us from sol 37 to sol 60. In the middle of the sequence the rover got itself in a very awkward position up on some rocks, and it took some considerable care and expertise to get it off safely. The T for technology tests were a variety of driving and maneuverability tests. The point here is, as you can see, they made the most of this little rover.

Sol 29 in that image has an asterisk to indicate that the activity took place on sol 29 but the images were taken on sol 30. I found I could work with these images and the map we saw earlier to put the rover locations and route unambiguously on a map, improving on what could be done at the time. We will get to that after the next 2 pages of these rover images.

Sojourner's sols 24-36 in the same format. I made the rover stand out by increasing contrast relative to the rest of each image. For scale in these figures, Sojourner is 63 cm long, 48 cm wide and 28 cm high. W denotes wheel abrasion experiments, which involved rotating just the right middle wheel of the rover. It carried nickel, platinum and aluminum plates. As the wheel turned the amount of wear was estimated from changes in reflectivity measured by a light sensor.

Here is the next section of the Pathfinder mission story - What Sojourner did between sols 15 and 23. These panels show motions and annotations indicate where various experiments were made. Soil mechanics experiments involved keeping 5 wheels fixed and rotation the sixth to estimate how hard the surface was. APXS measured composition. We will look at more measurements later.

Pathfinder didn't just image tracks, it also imaged the rover itself, and here it was much more systematic. I started to put together sets of images to document sol by sol movements, to help with the mapping, and then realized just how useful it was to document the rover's activities like this. Here's the first page of images, like a storyboard for the mission. I will be doing this soon, I hope, for rovers on CLPS landers on the Moon.
